使用主管和 docker 运行 cron

Question

我遇到了一个遗留 Laravel 项目的问题。它使用主管和 cron 来运行计划任务，但似乎 cronjobs 不会运行（并且显然从未运行过）。

这是 Dockerfile：

FROM 704666026001.dkr.ecr.eu-central-1.amazonaws.com/laravel-prod

# Copy project
COPY . /var/www/html/

# Copy cronjob setup fro laravel scheduler
COPY docker/cron/cron.txt /etc/docker/cron/cron.txt

# Copy laravel queue worker supervisor conf
COPY docker/supervisor /etc/docker/supervisor/conf

RUN mkdir -p /var/www/html/storage/framework/cache/data \
    && /usr/bin/crontab -u www-data /etc/docker/cron/cron.txt \
    && chown -R www-data:www-data /var/www/html/

在 docker/supervisor 文件夹中，有两个文件： 一个名为 queue-worker.conf 的文件：

[group:laravel]
programs=laravel-worker
priority=30

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/html/artisan queue:work --sleep=3 --tries=3
user=www-data
numprocs=1
startsecs=10
autostart=true
autorestart=true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

还有 cron.conf：

[group:cron]
programs=crond
priority=40

[program:crond]
process_name=%(program_name)s
command=crond -f
user=www-data
autostart=true
autorestart=true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

并且文件 docker/cron/cron.txt 有一行：

* * * * * php /var/www/html/artisan schedule:run >> /dev/null 2>&1

docker 镜像确实构建没有任何错误。当我在本地运行它时，这是输出：

它确实显示“crond 进入运行状态”，但 cronjob 没有以任何方式运行。 有谁知道为什么？这个设置是否有效？

提前感谢您的帮助！

如果主管在一定时间内没有做任何事情，他们就会停止运行。

因此，使用 cron 您只能间歇性地运行任务。所以它被关闭了。
